couple of weeks ago I flew to Carlisle from Blackbushe and back in a day at approx 5 hours. Used a brief relief bag on the way!
A few days later I flew to the scilly Isles with stops at Bristol, Perranporth and Lands End. This totalled nearly just over 6 hours.
I prefer the long cross country flights because I feel like I'm really going somewhere and I am covering distances I definitely couldn't by car in the time.
My dream is to fly to S Africa one day!
